Abstract

Steel Melting Shop One (SMS-I) has 03 BOF converters with 135 tons capacity each. The SMS-II has 04 BOF converters with 180 tons capacity each and SMS-III with 1x160 ton EAF Furnace. India’s largest integrated complex intend in the near future to build SMS-IV and will reach 16 million tons of steel per year. The other side, common problems during operations of BOF happens like: Jam’s formation of blowing lance and converters mouth with dirty skirt. Efforts are made every day to avoid and reduce these effects and increase productivity and reduce costs. This present paper, the focus was enhanced blowing lance operation, reduction of lance jam and converters mouths jam of BOF shops. A new concept of lance tips was introduced for the same to improve more stable conditions during long life lance tips called “Slagless Clean Up cartridge”. The target of this work is shown new conditions to reach like: increase cartridges life, reduce jams around lance and mouth contribute for stable operations.
